Election observer effects: A field experiment in the Russian Duma election of 2011

• Presents results of a large field experiment in election monitoring in Russia.
• Results suggest that existing literature on the effect of election observers is too optimistic.
• Proposes a new research agenda focused on the circumstances shaping the effectiveness of election monitoring operations.

The literature on elections and election monitoring is divided between those who take a skeptical view, suggesting that monitors are often political rather than objective in their judgments, and those who see monitors as a real force for cleaner, more honest elections. Studies that use field experiments to look for the effect of monitors generally support the optimists, indicating that the mere presence of election observers can have powerful effects. This is surprising given the extent of the resources available to incumbents who wish to conduct electoral fraud. We present the results of an experiment in which 768 observers were randomly assigned to polling stations in 21 cities in Russia in the 2011 parliamentary elections. Unlike most previous studies of election observers, our results suggest that observer effects on turnout and vote for the ruling party are small. The results suggest the need to study more carefully the circumstances that shape the impact of observation missions.
